Answer : The correct option is, (c)
Explanation :
First we have to calculate the energy or heat.
Formula used :
where,
E = energy (in joules)
V = voltage (in volt)
I = current (in ampere)
t = time (in seconds)
Now put all the given values in the above formula, we get:
Now we have to calculate the heat capacity of the calorimeter.
Formula used :
where,
C = heat capacity of the calorimeter
= initial temperature =
= final temperature =
Now put all the given values in this formula, we get:
Therefore, the heat capacity of the calorimeter is,
One, three and five are correct.
Although if the second statement is saying that stars use gravitational force to support nuclear fusion which in turn produces energy then that would be correct, but I don’t think so :)
